Bring up for Odroid N2 (Meson G12B)

[martinayotte]

I've received my Odroid-N2 Dev Sample !

It came along eMMC and Realtek WiFi dongle.

eMMC was already stuffed with 4.9.162 kernel.

First boot went thru, then auto partition expanded and auto shutdown.

Second boot, I was able to login and start exploring ...

 

[TonyMac32]

I will begin playing with mainline on it, and look to see if any mainline u-boot work has been done at the same time. If so the goal would be to just lump it in with Meson64 and keep the kernel count down. On Amlogic we have the luxury of Balbes's media box images, so we don't have to fight with the vendor kernels.

@balbes150Is that available simply by switching to "tvbox" branch ?

I have not sent updates for a long time, there are a lot of changes, I need to make a PR (if it is still in demand)

Please, do it if you can spend time on that task, we wish to do kind of "board bring up" for Odroid-N2.

Also, I hate to use the current BSP 4.9.162 ... What is your version ?

Okay, I'll get the data ready tomorrow and send the PR. I'm using a 5.1 kernel

That is good news !

[JuanjoAr]

sadly im getting a lot of read errors from usb storage when using balbes build with kernel 5.1. im gonna reflash and test again

 

edit: usb3 are not yet supported in kernel, just saw again brad's post in page 1

I looked at the settings for N2 in the tvboxes branch. It uses a different partitioning scheme and the formation of the startup script, so you will need additional adaptation of the changes to do PR (and most importantly check how it will work in the real image).

 

[Poincare]

Hello, I have Armbian running on my N2.  I have installed OMV through armbian-config. There did not appear to be any errors; and, OMV is assessible via the web gui.  However, when I try to install NCP via armbian-config,  it just says "Loading install info..."  then goes back to the Softy screen.  I do not see any other errors.  I do not know where to look for what errors are preventing NCP from installing since armbian-config and my N2 seem to be functioning properly at the moment.  Does anyone know how to get NCP installed?

 

[martinayotte]

@balbes150 , thanks for your 5.1.0 image !

I've tried to enhance boot verbosity by adding "loglevel=7" in bootargs in /boot/boot.ini but it didn't worked since "cat /proc/cmdline" still showing original bootargs, it seems that bootargs from /boot/boot.ini is simply ignored ...

I wish to have more verbosity, because I'm unable to make it boot from eMMC, something must append during this last line and login prompt, since on eMMC it is not reaching the login prompt and it stuck at this "re-mount".

You can't have both at the same time. Not on Armbian and not on any other system unless you enforce virtualization, adjust ports of many shared services ...

I will check this option at myself and I will write result.

I've booted from SD, bring a copy of the image via SSH/SCP, then "dd if=Armbian_5.86_Odroid-n2_Debian_buster_default_5.1.0_20190514.img of=/dev/mmcblk0 bs=100M" ...

All is going normally build the image of N2 on the branch tvboxes ? I am not forming a uInitrd file. Is it a bug in my build environment or is it a common problem ?

In normal Armbian builds, the uInitrd is done as a post-install script when installing Kernel Deb with DPKG.

[balbes150]

Good news. I found an easy way to run Armbian and Libreelec system completely from USB to N2 (without using SD card or eMMC module).

For those who want to get this opportunity without waiting for the release of the SPI u-boot update , I can write a simple instruction how to do it through the UART console (it is very simple and takes only 2-3 minutes).

This you figured out about the "loglevel" ?

Checked at myself "loglevel=7" , the option works on both kernels. The image with the 5.1 kernel is written to a slow SD card, when set the level 7 , waited more than 20 minutes to start the system, but did not wait for the prompt to enter the login. In mode 5, "cat /proc/cmdline" shows the correct value in the arguments specified by "loglevel=5". You in what place to register this option ? Show the contents of "boot.ini"

Here it is :

ODROIDN2-UBOOT-CONFIG

setenv dtb_name "/dtb/meson-g12b-odroid-n2.dtb"
setenv bootargs "root=LABEL=ROOTFS rootflags=data=writeback rw console=ttyAML0,115200n8 loglevel=7 no_console_suspend consoleblank=0 fsck.fix=yes fsck.repair=yes net.ifnames=0"

# Set load addresses
setenv dtb_loadaddr "0x1000000"
setenv k_addr "0x1100000"
setenv loadaddr "0x1B00000"
setenv initrd_loadaddr "0x3700000"

# Load kernel, dtb

fatload mmc ${devno}:1 ${dtb_loadaddr} ${dtb_name}
fdt addr ${dtb_loadaddr}

# boot
booti ${k_addr} ${initrd_loadaddr} ${dtb_loadaddr}

and here is what /proc/cmdline is showing me :

root=LABEL=ROOTFS rootflags=data=writeback rw console=ttyAML0,115200n8 console=tty0 no_console_suspend consoleblank=0 fsck.fix=yes fsck.repair=yes net.ifnames=0

Maybe I should stop U-Boot and try "printenv" ? Maybe it is because it was previously saved and the modified /boot/boot.ini is ignored ?

What's in the launch logs ? Perhaps not all items are correctly added (changed). I use necessarily two partitions for external media. This ensures that users can easily change the settings on any PC (including Windows), when using one ext4 - there will be problems with changing the settings (edit boot.ini, etc.)

I added support for booting without having FAT partition so this is not the case. Legacy kernel boots fine.

The strange thing is that, althouth "loglevel=7" been added to /boot/boot.ini, here is the early boot output saying :

[    0.000000] Kernel command line: root=LABEL=ROOTFS rootflags=data=writeback rw console=ttyAML0,115200n8 console=tty0 no_console_suspend consoleblank=0 fsck.fix=yes fsck.repair=yes net.ifnames=0

EDIT: Another weird thing : I've decided to use the workaround by adding chosen/bootargs node to the DT, as we are doing on other boards, recompile the DTB, and reboot ...

Strangely, the "loglevel" is been discarded there too, and doing "cat /proc/device-tree/chosen/bootargs" revealed that it is discarded there too :

 

cat /proc/device-tree/chosen/bootargs 
root=LABEL=ROOTFS rootflags=data=writeback rw console=ttyAML0,115200n8 console=tty0 no_console_suspend consoleblank=0 fsck.fix=yes fsck.repair=yes net.ifnames=0

EDIT2: Ok ! I found my stupid error : I was leaving the eMMC plugged, and although booting from SDCard, U-Boot was taking the boot.ini as well as DTB from eMMC, which they were still at original states !

Is it when starting from SD card or when recording to eMMC ?

 

I downloaded the scripts to activate the system startup from USB. The order of use (so far it is checked only with kernel 5).

1. Burn image to USB.

2. Download the files and add to the image.

3. Switch to start u-boot with SPI.

4. In the UART console, stop startup. (CTRL+C)

5. Execute the command.

 

usb start

fatload usb 0 3000000 n2_autoscript

autoscr 3000000

 

At the end of the script, the system should shut down. Include, if correct, should begin loading and operation of the system with the USB.

Unfortunately, my SPINOR seems to be stuffed with a U-Boot that doesn´t have keyboard check, I've tried <space>, <return> and <ctrl-c>, none of them worked.

So, I went back pluging the eMMC, and try it there, but here is the execution :

After that, I've rebooted, it seems to start booting from USB, but stuck without reaching login prompt again ...

I've added "loglevel=7" in boot.ini, and also in boot.cmd I've created to redo boot.scr using mkimage.

But no success : booting from USB stall before login prompt without clue ...

 

EDIT: It has finally booted, but without verbosity, and this time, it was present in /proc/cmdline.

I am checking on the latest version of the SPI image (20190417).

 

After adding the launch from USB from u-boot SPI , the launch of all systems from both SD card and eMMC works perfectly in u-boot SPI. Thus, there is no need to add u-boot to SD card and EMMC, everything works with u-boot SPI.

According to the log , you added support for USB in u-boot, which is located on eMMC. If you disable the eMMC module, you will not be able to start from USB. To fully support the launch from USB without any other media, it is necessary to add the update to the u-boot SPI.
